Mvs/Xa JCL: A Practical Approach (Merrill Series in Computer and Information Systems)

A unique new text for programming courses, one of the few in the field to concentrate specifically on MVS and JCL. Written to be a real "learning" tool, and not simply a reference manual, this text offers a step-by-step spiral presentation of topics discussing each concept several times, adding additional details as the text progresses until the material is completely understood. Concentration on the most frequently used aspects of JCL, together with a focus on real-world standards and specifications, makes this a very practical guide for preparing students to meet industry standards for JCL programming. Features includes an abundance of hands-on exercises and programming assignments. Advanced topics and concepts such as VSAM data sets and IBM utility programs are dealt with in an appendix.
